a math phrase that includes numbers, letters and operations signs but no equal sign
What is an expression
4(x+2) - 2x +5
What is 2x + 13
2x + 1 = 9
What is x=4
DOUBLE JEOPARDY (double points)
4(x-2) + x -4x =-8
4x-8 + x - 4x = -8
Your correct answer should include the next step AND what the next line should look like
What is combine like terms
4x + 1x -4x = 5x - 4x
so
1x -8 = -8
a line that bisects two parallel lines is called
What is a transversal

What is a term
5x - 3x + 2(x +6) - 6
What is 4x + 6
2x + 4x - 3x = 18
What is x =6
1 - x/3 = 12
What is subtract 1 from each side
Solve this:
If Davian has $3 and he saves $1 per week how many weeks will it take him to save $12?
3 + 1x = 12
9 weeks
3x and 15 x or
2y2 and 27y2 or
23 and -12
What are like terms
1p + 1p + 2t + 3t+ 1p + t -36 + 32
What is 3p + 6t - 4
2/3 x - 4 = 8
x =18
1 - x + 12 + 2x = 4
13 + x = 4
What is subtract 13 from both sides
DOUBLE JEOPARDY (double points!)
What is the difference between an expression and an equation?
An equation has an equal sign, but an expression does not.
a letter that represents an unknown value
What is a variable
2x + 2x2 + 3x2 + 4x - 16 + 22 -3x2 - 5x
What is 1x + 2x2 + 6
1 - x/5= 12
What is x= -55
4(x - 2) + 3x = 20
4x- 8+3x =20
7x - 8 = 20
Add 8 to both sides
Solve this
